Application December 16, 1946, Serial No. 716,639

s Claims (-01. 308-84) The invention relates to railway axle journal lubricators of the type illustrated in patent to the present inventor, No. 2,378,407, issued June 19, 1945, in which lubricant is pumped from the bottom of the axle box to the face of the journal and is spread over the lower portion of the latter to be carried by the journal to the bearing resting on the upper portion of the journal. The main object of the invention is to provide a journal engaging member for operating the pump having a substantially large journal engaging face which aligns itself with the end of the journal for full contact therewith and which resists wear.

This and other objects will be apparent to those skilled in the art from the following description and accompanying drawing, in which- Figure 1 is a longitudinal vertical section through an A. A. R. (American Association of Railroads) journal box and shows a lubricator pump embodying the invention, adjacent portions of the journal and pump being shown in elevation.

Figure 2 is a vertical transverse section through the journal box taken approximately on the line 2--2 of Figure 1.

Figure 3 is a horizontal longitudinal detail section drawn to enlarged scale and taken approximately on the line 3--3 of Figure 1 and shows a journal engaging member constructed according to the invention.

Figure 4 is an end view, looking in the direction of the arrow, of the journal engaging member shown in Figure 3.

The journal I forms the end portion of an axle and is provided with a collar 2. The journal box has side walls 3 and a bottom wall 4 with its outer end curved upwardly as at 5.

The mechanical lubricator consists essentially of a pump '1 and a distributor 8. Pump I comprises a substantially rigid body portion 9 resting on the box bottom wall and having radially extending inclined ears I to which are pivoted a series of compound levers II and I2, the upper ends of the latter mentioned levers being provided with substantially cup-shaped journal engaging members l3 engaging the end of the journal l and described more fully below. The inner ends of levers .l l engage the outer ends of plungers M which are thrust outwardly by coil springs l5. Play of the axle and journal longitudinally of the box reciprocates levers II and I2 to impart movement to plungers M. Plungers I4 operate pistons (not shown) in the pump body to draw in oil provided in the lower portion of the box and to discharge it to distributor B.

Each journal engaging member l3 has its right hand end It enlarged, providing a substantially flat journal engaging face I! preferably hardened to resist wear. A recess l8 extends longitudinally inwardly of member l3 from the left hand end of the member and the inner end of recess I8 is concaved. The rounded end portion of lever I2 is received loosely in recess l8 and its tip He is seated in the concavity in recess 18 and centers the member on the lever. An aperture [9 extends transversely through member l3 and loosely receives a cotter pin 20 inserted through lever 12. Hence, member [3 is arranged for limited angular and longitudinal movement on lever l2. In normal operation, member 13 pivots on lever l2 so that. face I! aligns itself with the end of journal I and the entire face I! of member I3 engages the journalend. Also, lever [2 seats in the inner end of recess 18 so that thrust is exerted by member I3 directly on lever 12 and not through pin 20.

An oil vent 2| connects the inner end of recess l8 with journal engaging face I! to lubricate the interior of the recess.

The details of construction may be varied substantially without departing from the spirit of the invention, and the exclusive use of modifications coming within the scope of the claims is contemplated.

What is claimed is:

1. In a device for lubricating a railway journal including a pump operated by reciprocating movement of a pump lever efiected by play of the journal longitudinally of its journal box, an element having a relatively large, flat journal engaging face, and means attaching said element loosely to the pump lever and providing for limited 1ongitudinal and angular movement of said element relative to said lever.

2. In a device for lubricating a railway journal including a pump operated by reciprocating movement of a lever cheated by play of the journal longitudinally of its journal box, a member having a substantially flat wear resisting journal engaging face, and means attaching said member loosely to the end of the pump lever for movement relative thereto to provide full engagement of said journal engaging face with the journal.

3. In a device for lubricating a railway journal including a pump operated by reciprocating movement of a pump lever effected by play of the journal longitudinally of its journal box, a journal engaging element comprising a cup-shaped member loosely receiving an end portion of the pump lever and having a substantially fiat journal engaging face of wear resisting material.

4. In a device for lubricating a railway journal including a pump operated by reciprocating movement of a pump lever effected by play of the journal longitudinally of its journal box, a journal engaging element comprising a cup-shaped member loosely receiving an end portion of the pump lever and having a substantially fiat journal engaging face of wear resisting material, and

a pin extending through apertures in said cupment of said element on the pump lever, said element, when engaging the journal, abutting the end of the pump lever so that thrust is exerted by said element directly on said lever.

B. In a device for lubricating a railway journal including a pump operated by reciprocating movement of a pump lever effected by play of the journal lonigtudinally of its journal box, a journal engaging element having a recess therein, the inner end of said recess lbeing concaved,

means attaching said element to the pump lever providing for limited relative longitudinal and angular movement of said element on the pump lever, said element, when engaging the journal, abutting the end of the pump lever so that thrust is exerted by said element directly on saidlever, the tip of said lever being seated in the concavity in said recess and'centering the element ,on said lever.

'7. In a device for lubricating a railway journal including a pump operated by reciprocating movement of a pump lever efiected by play of the journal longitudinally of its journal box, a journal engaging element, means attaching said element to the pump lever and providing for limited relative longitudinal and angular movement of said element on the pump lever, said element havingan oil vent extending inwardly from its journal engaging face to lubricate the end of the pump lever, and said element, when engaging the journal, abutting the end of the pump lever so that thrust is exerted by said element directly on said lever.

8, A device adapted to be mounted on the end of an operating lever of a railway journal lubricator pump, comprising an element of Wear resisting material having a wide substantially fiat face at one side for engaging the end of a journal, and a part projecting from the opposite side of said element and provided with a recess for loosely receiving the end of the pump lever, there being a transversely extending aperture in said part at the sides of said recess, and a pin extending through said aperture from side to side of the part for attachment of the device to the pump lever, the aperture loosely receiving the pin to accommodate its inclination relative to the flat face of said element.
